Nope. My definition of fiduciary is a legal obligation of one party to act in the best interest of another.
FA's that charge AUM and claim to be fiduciaries really don't meet that standard. What obligation do they have to ensure you make the best investment decisions if they make of percentage of your investments regardless of how those investments perform? This is a conflict of interest if ever there was one.
What are you paying in AUM to your fiduciary?
